report page v2 with redesigned dropdown

FlatUI.css is the sheet with the styles for the drop-down. There are
also some switch and radio button styles that I think may be nice to
use down the line. It needs application.js and bootstrap-select.js in
addition to the FlatUI.css and some tweaks to style.css, mostly impacts
to H4 sizing. I searched the code to see where h4's were currently
being used and I think the changes I made to size it down on smaller
screens will actually help wherever else it is being used...
